HORACE E. MARTIN, OF ATHENS, GEORGIA.

AXLE.

Application filed June 26, 1915.

To all whom it may concern:

Be it known that I, HORACE E. MARTIN, a citizen of the United States, residing at Athens, in the county of Clarke and State of Georgia, have invented certain new and useful Improvements in Axles; and I do hereby declare the following to be a full, clear, and exact description of the invention. such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to axles for vehicles; and it consists in the novel formation of the axle skein and its fastening devices as hereinafter fully described and claimed.

In the drawings, Figure 1 is a side view of one end portion of an axle constructed according to this invention. Figs. 2, 3 and 4: are cross-sections through the axle, taken on the lines 2-2, 3-3, and 4 4:, respectively. Fig. 5 is a plan view of the forked end portion of the axle.

The main body portion 6 of the axle is preferably formed of wood, and it has a longitudinal slot or groove 7 in its underside. This axle portion 6 is preferably made of two pieces of wood secured together. A re-inforcing bar 8 of iron or steel is provided. This bar 8 is T-shaped in cross-section, and its web is secured in the groove 7 so that its base flanges 9 come under the bottom of the main wooden portion 6. A tapering skein 10 of any approved form is secured over each end portion of the parts 6 and S, and its bottom 11 is thickened where the flanges of the bar 8 bear on it. The end portions of the flanges 9 are cut away so that the web projects longitudinally beyond them. A tapering block 12 is provided, and it has a longitudinal slot 14 which fits over the projecting end portion of the web of the bar 8. The block is beveled diagonally at its inner end, and it fits against the end of the wooden portion 6 of the axle, and fills the smaller end portion of the skein.

The longest side of the block is arranged at the bottom side of the skein, and the block is secured to the web of the bar 8 by rivets 17. The outer end of the block has a screwthreaded spindle l8 and a shoulder 19, and the axis of the spindle is arranged parallel to the bottom of the axle flanges 9. A flanged nut 20 is screwed on the spindle 18, and 21 is a pin or cotter which prevents Specification of Letters Patent.

the nut from unscrewing. A collar 22 is screwed on the spindle 18, and has a counterbored end portion 24 which fits against and over the shoulder 19. The periphery of the collar is turned to the same size and taper as the end portion of the skein against which it fits, and it forms an extension of the skein. This collar also operates as a nut, and it holds the skein in place when the flanged nut 20 is removed. WVhen the axle box and the flange of the nut 20 becomes worn, the collar 22 can be removed and ground away on one side, so that all slack or play may be taken up. An axle constructed in this manner is inexpensive to make, and is very strong, and is easily repaired.

What I claim is:

1. In an axle, a body portion having a longitudinal groove, a re-inforcing bar T- shaped in cross-section and having its web secured in the said groove and projecting beyond the end of its base flanges and the said body portion, a skein arranged over the end portions of the said body portion and bar, a forked block which fits in the outer end portion of the skein and which is secured over the projecting end portion of the said web, said block having a spindle which projects from the skein, and fastening devices engaging with the said spindle and securing the skein in place.

2. In an axle, a body portion having a longitudinal groove, a re-inforcing bar T- shaped in cross-section and having its web secured in the said groove and projecting beyond the end of its base flanges and the said body portion, a skein arranged over the end portions of the said body portion and bar, a forked block which fits in the outer end portion of the skein and which is secured over the projecting end portion of the said web, said block having a shoulder and a screwthreaded spindle which projects from the skein, a collar screwed on the said spindle and having a countersunk portion which engages with the said shoulder, said collar forming an extension of the skein and bearing against it, and a flanged nut screwed on the said spindle and bearing against the said collar.

In testimony whereof I have affixed my signature.
